Meanwhile, another source close to the situation tells us that Smart received a phone call late last night telling him that things were done once and for all.

The decision apparently came in the wake of reports that Smart had been sexting with a transsexual he met through Instagram. Smart has denied all claims.

We're told that Smart was blindsided by reports this morning that the American Idol judge broke up with him months ago.

"Whether there is any truth to what is being reported or not, it's irrelevant. Jennifer did not trust him," our source tells us. "The relationship had not been right for a while. Smart was never going to be the love of her life, but he was fun and a nice guy to be around. It stopped being fun once his friendships with other people started to come to light."
